Abstract
Several symptoms are described in obstructive sleep apnea OSA including excessive daytime sleepiness depressive mood and neurocognitive dysfunction However few studies examined the relationship between objective physical activity quality of life and sleep parametersWe reviewed retrospectively data of 75 somnolent moderate to severe ApneaHypopnea Index 20 OSA patients Data of 5days actigraphy and polysomnography were analysed They all completed the Nottingham Health Profile questionnaire NHP Sleep parameters associated with physical activity and quality of life were assessedPatients were mainly obese mean BMI 36 and males 53 Controlling for age and BMI physical activity expressed as number of steps walked/day is associated with OSA severity in REM sleep p = 005 Subjective somnolence was not associated with reduced physical activity Regarding quality of life “sleep” “energy” and “emotional reactions” scored highest and patients evaluated correctly their activity impairment through the “mobility” item of NHP questionnaireLow level of physical activity is associated with increasing OSA severity in somnolent moderate to severe OSA patients but is not linked to subjective somnolence These patients describe concomitantly a severely impaired quality of life in several domains and the negative perception in the “mobility” domain is effectively related to an objective low level of physical activity
